Prone Lying Leg Curl

Lie belly down and loop a band around your right ankle, anchoring the other end to a door or support. Scoot away from the anchor to create tension. Tighten your core and bend your leg at the knee, bringing your heel toward your glutes as far as you can comfortably go. Slowly return your leg to starting position and repeat for 10 to 15 reps, then switch sides.
